Search for: [Description = "Geomyids are polyphasic with movement in simulated burrows recorded for all hours of a 24 hr cycle\; particular troughs or peaks in times of locomotor activity were not evident. Total percentages of locomotory activity per day oscillated at separate levels for the three genera tested \(one to ten percent for Geomys\; 10 to 20 percent for Thomomys\; and 30\-40 percent for Pappogeomys\). Temperature did not greatly effect the amount of locomotory activity or the length of extended locomotory activity periods."]
